We were moving to a new state after my husband had been out of work for many months and we had no money. In fact, we had to borrow money to reach our destination town. Anyway, it was my husband, two boys aged four and two, and myself, seven months pregnant  , in an old Volvo station wagon. We had been driving for two days in the middle of winter (that car's heater didn't work), and we had taken a route that was very _ . There was nothing around for miles-no cars, buildings or signs of civilization. Suddenly, our car started losing power and the gauges  went all out of order. We saw a light in the distance and managed to roll to a stop in front of this property that looked like a small simple house. Our cell phones had not gotten reception for many miles, and it was freezing outside, so I didn't know if we were going to make it out of this situation alive. My husband got out of the car to see if there was something he could do to get us rolling again, but it was not looking good. A short while later, a man came out of the house and spoke with my husband a bit before inviting us all into his home. He and his wife took us in, fed us, and made us feel at home as we struggled to find some way to get to our destination, which was still a few hours' drive away. We were able to call a friend and get a ride, leaving our broken car behind, but not before the couple gave us food and water for our journey. One week later, this dear sweet couple pulled our car all the way to our place and refused to take anything in return, except for us to pay it forward-and we have, and will continue to do it forever. We can learn from the text that the family  _  . A) had a hopeless future B) was in financial difficulty C) suffered from a company crash D) wanted to turn to their relatives for help

Picture the scene: You come home after work feeling too exhausted to cook -only to find a delicious meal worthy of a Michelin-starred restaurant waiting for you. It sounds like a fantasy, but it could be about to come true thanks to a robot chef developed by British scientists. Those scientists have come up with a set of robotic arms so smart that _ are capable of cooking meals all by themselves. The device will be sold from as early as 2017 as part of a purpose-built high-tech kitchen. Scientists at Moley Robotics spent almost 18 years developing the hands. According to its creators, the arms can chop, stir, whisk and baste well enough to recreate almost anything you would care to eat, whether it is a simple home-cooked supper, or a complicated creation designed by a world-class chef. The hands move a little slowly, hovering strangely above the work surface whenever they are not busy, but they imitate human movements closely enough that they can do things such as wiping a spoon on the edge of a pan to prevent drips. Mr Oleynik, who is leading the project, said, "All the things which are possible with the hand are possible here. There is no limitation. A lot of people want to go to Michelin-starred restaurants, but they are quite expensive and may be quite far from the home. This is an opportunity for people to enjoy very good food, and for a reasonable price. " The only cuisine that is off the robot's menu at the moment is sushi, which requires extremely steady pressure and nimble fingers to make, but the team plan to conquer that as well by the time it goes on sale. What can we infer from the passage? A) Hands of a robot chef can perform exactly like a cook. B) Robot chefs are available at shopping malls. C) Michelin-starred restaurants are suitable for many people. D) It is uncertain when the robot can cook all kinds of food.
